Summary

SIA NETVISION

Latvia · AI-generated

isp latvia residential access

The AS handle NOVA-ASN is held by SIA NETVISION.

What it's used for

  • The address space is registered under the netname NOVALAT-NET with registrant SIA NETVISION; DNet Administrative contacts.
  • The network announces 4608 IPv4 addresses across 4 prefixes and maintains 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.
  • As a Latvian ISP, the traffic consists of subscriber internet access, including residential broadband and business connectivity.

Notable

  • All four announced prefixes share the same registrant SIA NETVISION and netname NOVALAT-NET, confirming consistent ownership.
  • The inventory consists of four distinct IPv4 blocks with no IPv6 prefixes announced.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
